Really, I'm just looking for the current best practice.

As a update, I've just tried Debug::Trace as it is documented and I'm getting no output...

perl -MDebug::Trace=TL1ng::Parser::parse_string test_simple_auto.pl
[download]

TL1ng::Parser::parse_string() is called as a method on a TL1ng::Parser object from inside various methods in TL1ng::Base.

I can't figure out what I'm missing :(
